Tracing your Lineage

Yesterday whiles watching a program about the location of the Ark of the Covenant on the History Channel, I remembered an idea that I am working on about the interconnected of the human race. If a particular tribe, race, or culture wants to trace their cultural lineage, they must look for similarities in customs, belief, religious practices, and games of other tribes, race or culture.
In the program, the historian Professor Tudor Parfitt mentioned that his previous quest was to investigate the claims of the Lemba tribe of South Africa that they are Jewish. DNA testing did prove their claim to be correct, which Professor Parfitt later supported after investigating the route the Jewish slaves took when they left Egypt and measuring Jewish Cultural practices against the Lemba’s cultural practices.
